I've had the same thoughts. I live in a residential area though. One of the biggest problems I see is that I do not have 360 clear field of fire/surveillance capability & defensibility, the house is partially made of wood and will burn easily, offers no ability to cover/conceal, is way too approachible, etc, etc. I'd like to be some place more remote, but the ability to get there is a problem. My after action solution is dependent on the problem. If my truck runs, I'm leaving the house after supplies run out or the situation dictates it.
